The study employed a quasi-experimental pretest-posttest design with a control group and a six-month follow-up. The statistical population consisted of women aged 25–45 years with comorbid depression and anxiety who attended psychological counseling centers in Tehran in 2025 and had received clinical diagnoses from a psychiatrist and psychologist. Using purposive sampling, 60 eligible participants were selected and randomly assigned to Emotional Schema Therapy, Dialectical Behavior Therapy, and control groups, with 20 participants in each group. The Emotional Schema Therapy group received ten weekly 120-minute sessions, whereas the Dialectical Behavior Therapy group received eight weekly 90-minute sessions. The control group received no intervention during the study period. Data were collected using the 12-Item Short Form Health Survey and the Metacognitive State Questionnaire at pretest, posttest, and six-month follow-up. Data were analyzed using repeated-measures analysis of variance in SPSS version 27. Repeated-measures analysis showed significant effects of time, group, and the Time × Group interaction for quality of life, with F = 188.42, F = 11.84, and F = 20.06, respectively, all p &lt; .001. Significant effects were also found for metacognitive state, with F = 211.74 for time, F = 14.67 for group, and F = 22.81 for the Time × Group interaction, all p &lt; .001. Post hoc comparisons indicated that both interventions significantly outperformed the control group, while Emotional Schema Therapy produced significantly greater improvements than Dialectical Behavior Therapy in quality of life and metacognitive state. Treatment gains were largely maintained at the six-month follow-up. Both Emotional Schema Therapy and Dialectical Behavior Therapy were effective in improving quality of life and metacognitive state in individuals with comorbid depression and anxiety, although Emotional Schema Therapy demonstrated greater and relatively stable effects over time.</p> https://journals.kmanpub.com/index.php/psychnexus/article/download/6666/12346
